Perhaps because he felt that he had said something unnecessary, Zhao Ruoya coughed twice, concealed his embarrassment, and then continued as if nothing had happened: "The location I pointed out now has a fortification that is very important for the safety of the defense line. Before the construction of this fortification, there was no abnormality. Everything went very smoothly, the internal facilities had been installed, and even all kinds of materials had been stored, so the garrison troops could be fully allowed to enter."

As Zhao Ruoyi said, the figures on the sand table began to change. Starting from the pointing location, a passage extends out of the mountain. Then the passage forked partly upward and partly downward, forming underground spaces of different sizes, densely covering the entire mountain and underground, forming an amazing underground building complex.

"You actually hollowed out the entire mountain?" Even though Xu Changqing did not see the real thing, and just saw the small model built by the sand table in front of him, he still felt an inexplicable shock. Such a huge project, even if it was placed in the Three Realms of Kunlun, was built by immortals, demons and Buddhas with various magical powers and magic, was probably very difficult. However, these ordinary mortals in front of him had such a feat, which made Xu Changqing, who had extensive knowledge, feel a little unbelievable.

Xu Changqing did not hide the surprise on his face, and the people around him could see it clearly. They all showed a smug smile on their faces, as if this project was mined by them.

"Are you not afraid of hurting the earth's veins when you do this?" Xu Changqing questioned in surprise.

Mr. Song explained: "Some minor injuries are inevitable, but the main vein of the dragon vein is not serious."

"Isn't it a serious injury?" Xu Changqing glanced at Old Song. Someone looked at the others around him and said, "If there is no serious injury, then what are the difficulties you are facing now?"

"This difficult thing has nothing to do with the dragon vein." Hearing Xu Changqing's questioning, Zhao Ruoyi's face completely dissipated and he said in a deep voice.

Xu Changqing asked one after another: "How do you know that it doesn't matter? How do you judge it has nothing to do with it?"

"This..." Although Zhao Ruoyan was responsible for the management of the entire secret department, he did not know much about Feng Shui and metaphysics, and could not answer for a while, so he could only look at Mr. Song.

However, at this time, Mr. Song had no intention of responding. Instead, he looked at the sand table with his eyes as if he was in deep thought. He looked thoughtful.

"It shouldn't be a disaster caused by injury to the dragon vein." True Man Puji took the conversation at this time and rescued Zhao Ruoyan, saying: "When digging that day, we sent people to monitor the whole process. Even if there is excavation that must be damaged, we will use the object to cut off the section of the dragon vein first, and then dig it. The damage to the entire dragon vein is actually minimal."

"It's so small, just what you think." Xu Changqing said coldly: "The dragon veins are the bloodlines of the earth. The soil and rocks are like bones and muscles, and the floating soil of vegetation is almost equivalent to hair and skin. Now that the skeletal muscles have been hollowed out, how can bloodlines exist alone? I'm afraid even hair and skin will be... "

"Mr. Xu, you are just looking at this from the perspective of an onlooker. If you stand from our perspective, surrounded by enemies, but you are not able to do it and can only defend passively, what will you do?" Zhao Ruoyi interrupted Xu Changqing and said, "You think there will be problems in the future, but if you don't do this, once a war breaks out, there will be nothing in the future."

Although Zhao Ruoyan's words were a bit direct and his tone was very stormy, Xu Changqing was not angry, but instead fell silent, as if considering his words.

"Let's go back to the topic!" Feeling the atmosphere a little nervous, Mr. Song spoke and muddled everyone's attention back to the topic: "Mr. Xu's words just now were not wrong. Although we repeatedly checked every detail and repeatedly deduced, we thought there was no problem, but this matter was not absolute. At least from the current situation, it seemed to be related to the dragon vein."

Xu Changqing said a little impatiently: "What exactly is the problem you are facing? After saying so much, there is no specific content?"

"Let me say it! After all, I was there when the incident happened that day." Zen Master Guangyin took the initiative: "It was about a few years ago. At that time, the base had been fully completed and various materials had been stored in it. The first batch of garrison staff had also entered. I and several fellow Taoists did the final inspection of the mountain underground palace. I thought nothing was done, but I never thought that something happened on the third night. A large amount of supplies and personnel disappeared overnight. The area where the original underground palace was blocked by a stone wall. The original mountain turned into some old buildings covered with vines, and even the dragon veins changed overnight."

While introducing the situation, Zen Master Guangyin also injected magic power into the sand table to promote changes in the sand table. He saw that the mountains on the surface of the sand table had not changed at all, but the internal structure had changed significantly, especially the trend of the original dragon vein, which was completely shifted to the other side as if it was distorted by an invisible force, forming another dragon vein.

"How is this possible?" Xu Changqing did not feel too surprised when he saw this amazing scene, but he was a little confused.

Although the name of the dragon vein is scary, its essence is still the earth's spiritual vein. However, because this spiritual vein is in line with the fortune of a certain race and a certain country, this spiritual vein often becomes stronger or weaker with the rise and fall of the dynasty and tribe, and can also influence the human fortune.

In the Kunlun Three Realms, the trend of the left and right spiritual veins is not rare. When Xu Changqing built the Demon God Temple, the Immortal Palace directly extended a spiritual vein from Xuanyuantian and injected into the realm of the Demon God Temple. However, the situation in the Kunlun Three Realms is different from the current situation, because no matter how external force is used to transfer or extend the spiritual vein, the part that already exists in the spiritual vein will not disappear. However, the changes in the Qinling dragon vein shown by Master Guangyin are completely deviated from this common sense. The place where the dragon vein originally existed completely disappeared, and another dragon vein extends from another place. What's even more strange is that the dragon vein has undergone such a huge change, but the main trend of the dragon vein has not changed, giving people the feeling that this dragon vein is a real dragon. It has just slept for a long time and turned around, and the direction of the head and tail has not changed at all.

Thinking that Xu Changqing was completely unbelieving what was happening in front of him, Mr. Song immediately explained: "This is the result of the only remaining geometric trends in China's success. I have checked it a few times afterwards. Although there are some differences in details, the overall picture is consistent with this dragon vein diagram."

Xu Changqing was silent for a moment, and suddenly felt something and asked, "When did this happen?"

The four of them thought about it and soon reported an accurate time. After hearing this, Xu Changqing found that the time when the dragon veins of Qinling Mountains changed was very close to the time when he returned to the secular world.

"Coincidence? Or..." Xu Changqing thought for a while, but there was no strangeness on his face. He continued to ask Zen Master Guangyin: "What happened later?"

"This happened too suddenly at that time, and everyone was caught off guard. Everyone wanted to escape there, and no one could notice anything else. I was ashamed of saying that the Buddha's heart was still and everything was not invaded, but in front of this world, it was no different from those ordinary people." Zen Master Guangyin said self-deprecatingly.

Zhao Ruoyi took the conversation and continued: "There is nothing to say later. Just as Mr. Xu goes to see it, you will know. In short, the Qinling Fortifications have been completely destroyed, and the materials originally stored there have been lost there, and the personnel losses are also a lot. The superiors attach great importance to this matter and specially sent us to deal with this matter. Our department sent more than 30 people and the army sent hundreds of elite troops. In the end, none of them came out from there. Until now, we only know that the dragon vein has changed. As for the specific situation in the original fortifications, they are not very clear." As he said that, he opened an iron cabinet next to the table with the key, took a folder from it, and handed it to Xu Changqing and said: "But several martyrs risked their lives and mapped the situation outside through a round light magic weapon, and took a photo by us."

Xu Changqing was not polite, so he took the folder and opened it to take a look. Most of the photos were covered with green vines and stones. These buildings were different from all known architectural styles in the world in terms of style, such as thin and thick rock plants at the bottom, twisted archways, prism-shaped roofs and eaves, etc. In short, all the buildings looked so weird. These weird buildings did not attract Xu Changqing's attention, but in the last few photos, Xu Changqing's eyes stayed for a moment.

The images on these photos are all in the same place, but the location is slightly different. A neat underground passage was cut off in the waist. There was no sign of the opposite shore in front and the abyss at the bottom. However, under the abyss was a palace shining with white light. This palace resonated with the soul fragments of the ancient demon godque that had not been completely digested in Xu Changqing's body.

"This..." Xu Changqing picked out these photos and asked.
